BACKGROUND

Embodiments herein generally relate to methods and systems for dynamically changing the identification of a server and/or ports in a mesh network based on an internal secret.

Conventionally, edge servers and Internet of Things (“IOT”) devices, or electronic devices that access the Internet through a network, are deployed in a public network where the edge servers communicate with the IOT devices over the public network. As examples, cameras can be deployed with internet access, smart grid devices that similarly have internet access, remote monitoring of assets, virtualized radio networks and 5G, cloud gaming systems, autonomous vehicles, etc. all present access points to the public network.

Because IOT devices and accompanying systems include direct internet access, significant security risks are presented in the form of surface attacks from hackers. In particular, any hacker may use the public network in an attempt to access the edge servers or IOT devices to obtain user information. As the number of these system grow in magnitudes, so do the risks associated from these surface attacks.

System Overview

Provided is a system in a mesh network that provides a communication path between two electronic devices, where a name of a receiving device, including a server, port of a server, etc. is continuously and dynamically changed based on a shared secret. The name generation and updating is based on the shared secret provided as a result of keys (e.g. public keys and private keys) related to the electronic device identifier, or name. The keys are utilized to derive the shared secret that is unique to each electronic device. In one example, the keys are utilized with an elliptic curve Diffie-Hellman algorithm to determine the shared secret for each electronic device. The derived name can only be utilized for a determined period of time. In particular, a TOTP is provided that is utilized to generate a token to provide access to the communication path.

FIG. 1 illustrates a system 100 implemented in accordance with embodiments herein for dynamically changing the identification of receiving devices including servers, ports, access point, etc. in a mesh network setting. The system 100 includes one or more electronic devices 110, or client devices, that manage and otherwise provide access to one or more receiving devices 120, where the electronic devices 110, and server 120 communicate through a network 130.

The electronic device 110 may represent various types of electronic devices including, but not limited to, personal computers, tablet devices, laptop computers, embedded appliances (e.g., thermostats, home monitoring systems, and the like), smart watches, medical devices, vehicles, digital assistants, and an entire array of other smart consumer goods. Each electronic device can include one or more processors 112, memory 113, a display 114, a user interface 115, a network communications interface 116, and various other mechanical components, electrical circuits, hardware and software to support operation of the electronic device 110. The memory 113 includes an operating system and instructions to implement the processes described herein. The memory 113 also stores one or more application programs to implement a security application 118.

Each receiving device 120 can represent a server, port of a server, access point, second electronic device, or the like. The receiving device 120 can also include one or more processors 122, memory 123, a network communications interface 126, or port, and a security application 128. The memory in one example may include one or more data stores containing data, information, instructions, videos, photos, software, programs, or the like related to the user and the electronic devices 110. The receiving device 120 may represent a single computer system or a collection of computer systems located at a common location or geographically distributed.

The receiving device 120 and/or the network communication interface 126, or port, can have a receiving device identifier 127 associated therewith that can be continuously, or dynamically updated by the security application 128 utilizing the methods and processes described herein. The receiving device identifier 127 can be a machine friendly name, user friendly name, etc. In one example, the machine friendly name is machine based, and can be fc9cec9e.d6240ec6.df6845a0:7623. Alternatively, a user friendly name is word based, and can be frozen.pier.whisper.76233. In example embodiments, the security application 128 based on a shared secret, and an amount of time, dynamically changes the identifier 127 such that only an electronic device that also can generate the shared second can correctly identify the name of the receiving device at a given time. In one example, the machine friendly name can be changed from a first name fc9cec9e.d6240ec6.df6845a0:76233 to a second name 26069ce4.e8f024c8.197efa47f5:8765. Alternatively, the first name could be changed from frozen.pier.whisper.76233 to a second name hallway.seem.dance:8765. As a result, any hackers attempting to access data, information, etc. of a user from the receiving device 120 is not able to access the receiving device 120 as a result of not having a public key to be able to provide the shared secret. Consequently, an additional layer of security is provided for the receiving device 120 and data, information, etc. on the receiving device 120.

The security application 128 can also communicate with electronic devices 110 through one or more networks 130 to provide access to the data stores of memory. The network 130 may be utilized to communicate a public key, so the electronic device can obtain the identifier 127 of the receiving device 120. The network 130 may represent the World Wide Web, a local area network, a wide area network and the like.

FIG. 2 illustrates a functional diagram of portions of the system of FIG. 1 as well as a first example of certain data, information, and content conveyed in accordance with embodiments herein. In particular, in the example embodiment of FIG. 2 , the system 100 is implemented as described herein to run the security application 118 on the electronic device 110, and the security application 128 on the receiving device 120. In particular, the electronic device 110 and the receiving device 120 communicate on a periodic basis in order to share a secret. In one example, the secret is provided based on an elliptic curve Diffie-Hellman (ECDH) algorithm.

For example, a user 204 provides a first public key 206 and a first private key 208 to the electronic device 110 to communicate with the receiving device 120 over the network 130. The public key 206 and private key 208 in example embodiments can include a string of numbers, a string of letters, etc. that can be utilized with a cryptographic algorithm 212 to obtain cryptographic data at the receiving device 120. The first public key 206 is considered “public” because the first public key is configured to be communicated through a public network 130 where third parties may have access to the public key, whereas the private key 208 is considered private because the private key 208 is configured to remain at the electronic device 110 and not be communicated over a public network 130. In this manner, the private key 208 is unique to the electronic device 110 and not communicated over a public channel of communication.

The cryptographic data is any data obtained by utilizing the cryptographic algorithm 212 before the data is shared or communicated. Cryptographic algorithms can include Diffie-Hellman algorithms, Rivest-Shamir-Adleman algorithms, asymmetric algorithms, symmetric algorithms, hash functions, secret key algorithms, public key algorithms, data encryption standard algorithms, triple data encryption standard algorithms, advanced encryption system algorithms, or the like. Cryptographic data can include files, documents, passwords, personal information, emails, electronic messages, text messages, videos, pictures, etc. The cryptographic data is stored in the memory of the receiving device 120; however, a user of the electronic device desires the cryptographic data to remain secret.

The receiving device 120 can have a second public key 216 and a second private key 218, along with a cryptographic algorithm 212 and the cryptographic data. Each of the second public key 216 and second private key 218 can be a string of numbers, a string of letters, etc. that can be utilized with a cryptographic algorithm 212 to generate a shared secret that is utilized to gain access to the cryptographic data. Optionally, the first public key 206 and second private key 216 are utilized together by a cryptographic algorithm 212 to generate the shared secret at the receiving device 120. Similarly, the second public key 216 and first private key 208 can be utilized by a cryptographic algorithm 212 to generate the same shared secret at the electronic device 110. The shared secret in example embodiments may be a string of numbers, a string of letters, a string of letters and numbers, or the like. The shared secret in one example is generated by a hash function including 256 bits. In other examples, a hash function, or other algorithm including 16 bits, 32 bits, 64 bits, 128 bits, or the like forms the shared secret. Because the private keys 208, 216 are not communicated over the network 130, along with the shared secret being generated by a cryptographic algorithm 212, a third party is unable to obtain the shared secret.

In the example of FIG. 2 , the shared secret is then used in combination with determined time periods for providing a dynamically changing identifier 127 of the receiving device 120 and communication interface (e.g. port(s)), where the identifier 127 is continuously updated over time. Based on the shared secret and a determined time period the security application 118 of the electronic device 110 and the security application 128 of the receiving device 120 generate a time-based one-time password (TOTP) 224 used to access the receiving device 120 or communications interface 126 of the receiving device 120. For example:

val_1=TOTP(SHA256(shared secret+time period))

val_2=TOTP(SHA256(val_1))

val_3=TOTP(SHA256(val_2))

port=TOTP(SHA256(val_3))

where val_n and port are the names of the receiving device or communication interfaces generated, SHA256 is a 256 bit hash function derived using the shared secret and the determined time period. The determined time periods can be 10 seconds, a minute, an hour, a day, a week, etc. The TOTP 224 is a password that is generated and can be used during the determined time period to access the receiving device 120 and is representative of the identifier 127. The TOTP 224 can be a domain name, machine friendly name, a user friendly name, or the like. In one example, a machine friendly name can be generated and matched to names in a dictionary, or other source material, to convert the identifier 127 into a user friendly name.

Once the TOTP 224 is used, the determined time period is automatically ended such that the TOTP 224 will not allow access to the receiving device 120 after communication with the receiving device 120 ends. Once communication with the receiving device 120 ends, a new determined time period begins resulting in the generation of a new TOTP 224. In one example, a knock function can be provided to limit the number of attempted entries of the TOTP 224 during the determined period. In one example the number of attempts is five (5), while in another example, the number of attempts is ten (10).

Upon entering the TOTP 224, a token 226 that is based on the identifier 127 of the receiving device 120 is provided for accessing the receiving device 120. The token 226 can be a series of bits that in the example embodiments are representative of the identifier 127. The token 226 in example embodiments includes a length dependent on the identifier 127 of the receiving device or communication interface. Therefore, in one example, the token length is dependent on the dictionary based terms in a user friendly name. Optionally, the token length depends on a machine friendly name. To this end, the token 226 matches the range associated with the name. In this manner, with the token 226 the electronic device 110 may communicate over the public network 130 with the receiving device 120 to obtain and communicate cryptographic data. Because the identifier of the receiving device 120 or receiving device communication interface 126 continuously updates, an additional level of security is provided. To this end, a hacker upon realizing such an extra level of security exists, will be encouraged to spend time attempting to obtain cryptographic data from another receiving device, and/or will become frustrated with attempts to obtain cryptographic data from the receiving device.

FIG. 3 illustrates a process 300 for dynamically updating an identifier of a receiving device when communication is desired via a publicly available network. In one example the system of FIG. 1 and/or the system of the functional diagram of FIG. 2 are utilized to implement the process 300 of FIG. 3 . To this end, the process may be implemented by one or more processors of an electronic device and/or server by executing instructions stored in a memory, including at least some instructions related to or associated with a security application or the electronic device or receiving device. In example embodiment, the receiving device can be a server, communications interface of a server such as a port, access point, second electronic device, or the like.

At 302, one or more processors of an electronic device obtain a first public key and a first private key associated with a shared secret. In one example, a user inputs the first public key and first private key via a communications interface, input device, or the like. The communication interface can include a USB port, wired connection, wireless connection, communications port, or the like. The input device in example embodiments can include a touch screen, keyboard, mouse, voice activated controller, etc. In one example, a provider provides the first public key and first private key, security application, cryptographic algorithm(s), including hardware and software, etc. to the user. The first public key is configured to be communicated over the network, while the first private key is configured only to remain at the electronic device.

At 304, one or more processors of a receiving device obtain a second public key and a second private key associated with the shared secret. In one example, a provider accesses the receiving device and inputs the second public key and second private key via a communications interface, input device, or the like. The communication interface can include a wired connection, wireless connection, communications port, or the like. The input device in example embodiments can include a touch screen, keyboard, mouse, voice activated controller, etc. In one example, a provider installs the second public key and second private key, security application, cryptographic algorithm(s), including hardware and software, etc. onto the receiving device. The second public key is configured to be communicated over the network, while the second private key is configured only to remain at the electronic device.

At 306, the one or more processors of the electronic device communicate the first public key to the receiving device over the network. In one example, the electronic device prompts the user to communicate the first public key through the network to obtain access to the receiving device. In another example, upon attempting to access the receiving device, the one or more processors of the electronic device automatically communicate the public key through the network to the receiving device.

At 308, the one or more processors, in response to receiving the first public key, communicate the second public key through the network to the electronic device. In one example, the receipt of the first public key at the receiving device starts a determined time period to be utilized in association with the shared secret to generate an identifier for the receiving device.

At 310, the one or more processors of the electronic device determine the shared secret based on the first private key and the second public key. In one example, the first private key and second public key are utilized in a cryptographic algorithm to result in the shared secret. In one example, the cryptographic algorithm is a ECDH algorithm. In other examples the cryptographic algorithm can be a Rivest-Shamir-Adleman algorithm, asymmetric algorithm, symmetric algorithm, hash function, secret key algorithm, public key algorithm, data encryption standard algorithm, triple data encryption standard algorithm, advanced encryption system algorithm, or the like. The shared secret in one example is a string of numbers. In another embodiment the shared secret is a string of letters. In yet another example, the shared secret is a string of numbers and letters. In other examples, the string includes 1024 characters, 512 characters, 256 characters, 128 characters, etc.

At 312, the one or more processors of the receiving device determine the shared secret based on the second private key and the first public key. In particular, as the one or more processors of the electronic device determine the shared secret, so do the one or more processors of the receiving device. In shared secret can be determined, derived, etc. in any manner, including as described in relation at 310.

At 314, the one or more processors of the electronic device determine a TOTP related to an identifier of the receiving device. Based on the shared secret and determined time period, a cryptographic algorithm, hash function, etc. can generate the identifier. In one example, the identifier is a machine friendly identifier. In another example, the machine friendly identifier is converted into a user friendly identifier. To provide the conversion, the TOTP is associated with a source material, such as a dictionary, to modify the TOTP to generate a user friendly identifier.

At 316, the one or more processors of the receiving device determine a TOTP related to the identifier of the receiving device. Based on the shared secret and determined time period, a cryptographic algorithm, hash function, etc. can generate the identifier. In one example, the identifier is a machine friendly identifier. In another example, the machine friendly identifier is converted into a user friendly identifier. To provide the conversion, the TOTP is associated with a source material, such as a dictionary, to modify the TOTP to generate a user friendly identifier. In example embodiment, the TOTP may be communicated to the user via an electronic message, text message, presented on an output screen, communicated to a different electronic device of the user, or the like.

At 318, the one or more processors of the electronic device prompt the user to input the TOTP. The prompt in one example is a prompt box requesting the TOTP be typed into the prompt box. Optionally, the prompt may include a knock, or number of attempts to accurately input the TOTP. The number of attempts may be three, five, ten, twenty, etc. If a user is unable to provide the correct TOTP in the number of attempts, the prompt will no longer allow additional attempts. In one example, no additional attempts are allowed for a determined period of time. In another example, a provider, or third party, must be contacted to allow additional attempts. In yet another example, an electronic message, text message, etc. is automatically communicated to another electronic device of the user, and/or a third party service provider to communicate that the TOTP attempts have failed. In this manner, if an undesired third party gains access to the electronic device of the user and is attempting to guess at the TOTP, the user and/or third party provider are alerted.

At 320, the one or more processors of the electronic device generate a token associated with the identifier based on the TOTP. The token is configured to be of a length or range associated with the identifier, including a machine friendly name, user friendly name, or the like. The token is configured to be communicated through the network to gain access to the receiving device.

At 322, the one or more processors of the receiving device receive the token and in response provides a communication path through the network between the receiving device and the electronic device. In particular, without receiving the token, the receiving device does not allow the electronic device to access any cryptographic data secured within a database, memory, etc. of the receiving device. In this manner, only an individual with the first public key can access the receiving device. In addition, by dynamically updating the identifier of the receiving device, a hacker can no longer take advantage of a static receiving device name in attempting to obtain user cryptographic data, improving security for the user.
